The most recent and relevant important date is September 2, where teams must reduce their rosters from 90 players to 53 by 3 p.m. CT.

The Kansas City Chiefs’ final preseason game is August 31, which means the team will have just two days to determine which 37 players to let go.

Previously teams would have to cut down from 90 players to 75 prior to game four, and then go from 75 to 53 after the final preseason game. However, the rules were changed at this year’s league meetings.

One important date to keep an eye on during the regular season is October 31, where the trade deadline hits at 3 p.m. CT.

Here are some notable dates in 2018:

January 1: From this date until May 3, teams can exercise fifth-year options on 2015 first-round picks. This includes cornerback Marcus Peters, whose option the Chiefs will likely exercise.

January 6-7: Wild card playoffs

January 13-14: Divisional playoffs

January 20: East-West Shrine Game

January 21: AFC and NFC Championship Games

January 27: Senior Bowl

January 28: Pro Bowl

February 4: Super Bowl LII

February 20: From this date until March 6, teams can designate franchise or transition tags. There really aren’t any Chiefs players that could earn the franchise tag in 2018, but the biggest candidates would be defensive lineman Bennie Logan, punter Dustin Colquitt or kicker Cairo Santos.
